What was the chief goal of allied leaders during ww2? what strategy did they evolve to meet this goal?

The main goal of the Allied leaders during the Second World War was to conquer the Axis power (which was headed by Adolf Hitler) and promote world peace. The goal was born as a reaction to the offensive and unprovoked attack upon the world by the Axis power. The Allied countries which include the United States, Great Britain, Soviet Union, and China came together and resolved to strategize on how to defeat the Axis power.    

The strategy adopted by Allied leaders in achieving the goal of defeating the Axis power was to restructure her military in such a way that a military technique known as Leapfrogging (which involved isolating the stronghold of the Axis military while taking proactive steps to vanquish and take over strategically important territories controlled by the Axis power) was adopted and implemented.

Hello there!

The Korean war ended with two different kind of results. A good result, and a bad result.

One of the good result is the fact that South Korea remained free from communist control with the help of United States.

One of the bad result is the fact that South Korea and North Korea split and they used to be one nation but now they are two enemies.

I hope this helps!~ Let me know if you have more questions about this.
